Question I need advice on my GPU temps ?

I have a Gigabyte 3080 10GB that seems to be running hot no matter what I try. I’m at the point where I have “No Man’s Sky” set to the absolute lowest settings (@1440p) and my card is running in the high 70s (Celsius) with the hotspot often topping 83C, according to HWInfo.

My system is in a Lancool II chassis with 3x120mm front intake, 2x120mm top exhaust, and 1x120mm back exhaust. The power supply is flipped so it pulls air from beneath the case. All the case fans are Noctua NF-P12 PWM, which I have hooked up to fan hub and running at max rpm.

My temps just suck. I don’t know what I’m doing wrong. I have everything torn down at the moment for normal cleaning, so I’m looking for options. There’s not really any place to add fans. It’s been suggested to me to redo the paste/tape on the GPU, which I’m willing to do, but I’ve never done before, so I’m a little hesitant.

I had to reformat recently, so my fan curves are stock. Any advice on properly setting those would be appreciated too.

Specs:
Mobo: MSI B550 MAG Tomahawk
CPU: Ryzen 7 5800X3D
GPU: Gigabyte 3080 10GB
RAM 32GB (2 x 16GB) 3200
Storage: M.2 SSD
OS: Windows 11

Thanks!
 
If possible take some photographs showing the inside of the case, the fans, etc..

Edit the photographs to indicate airflow directions.

Post accordingly.

“I have everything torn down at the moment for normal cleaning…”

There’s nothing currently in the case, hence why I linked the Lian-li webpage. I can try to cobble something generic on my phone if the website doesn’t convey the layout well enough…

You are saying these temps are while on a bench in open air?

What is ambient in the room?
No, I’m saying those are the temps while the system is together. I simply stated I have my system currently torn down to clean it. While it’s torn down, I’m looking for advice before I put it together again.

EDIT: This is on lowest possible graphics settings.

EDIT: In any case, room is roughly 70-80F.

How are mid-70C and 83C “REALLY good” temps on LOWEST settings on a 3080?
Not disastrous for that GPU either, It looks like it's well ventilated case, only thing left is to reapply paste and pads in the GPU.
To check for problems with ventilation, close the case and set all fans to maximum. If temps get drastically better, fan curves are wrong. You can also try to undervolt and/or limit GPU power.

Normally the fans are connected to a hub and run full-tilt all the time because the noise isn’t an issue.

I’ve ordered the vertical riser kit made by Lian li to reorientate the card, which will allow me to get two fans directly underneath it.

In terms of repasting/padding, I’ve never done that with a GPU before. Any advice? I’ve started to read up on the process and I’m worried I’m going to pick the wrong size/thickness pads and/or install them wrong.

Maybe worthwhile to find somebody experienced to re-paste graphic card, it can be tricky, not only the job but also finding right materials, there is no standard for all but case by case even with same manufacturer and model.

A 13C delta is good; some cards have up to 20C, and the latter's still acceptable.
Hot spot is 83C out of 110C... very good.
Presets aren't always optimal; 'lowest' doesn't always yield the easiest workload on the hardware.
You're running 1440p - it's no 4k, but that's still ~78% more pixels to drive in the game than 1080p; not insignificant, even at the lowest preset.

21-27C then... but the case ambient is always higher. What's that going to be at, once the GPU is running for a few minutes? Because, that's what the gpu is going to be cooling off with, not the cooler room ambient.

Thanks for the data. That puts things into a better perspective.

So, would it make sense to allow GeForce Experience to optimize the game for me in terms of settings? I’ve always been skeptical of the utility outside of updating drivers.

I agree with you, but sadly, I don't think GFE is reliable. It optimizes settings through crowdsourcing, which doesn't work that well in practice, 'cause there's too many independent variables at play.
 
How old is the card? If heat has increased over time due usage it's pretty normal and might need thermal paste/pads to be reapplied. As a shortcut before repasting you could undervolt your GPU which is a very good way to decrease power consumption, heat and increase performance. How to undervolt 3080 using MSI Afterburner
Rev. 2 was released in September 2020. I purchased sometime in 2021.
 
I remember back in the day there were complaints about Gigabyte RTX cards running hot but i'm not sure if it was the 2000 or 3000 series.
Were you always looking at temps and noticed a change or did you have a problem and then looked at the temps?

Your comments aren’t helpful and seem to border on antagonistic. You can move onto another thread.
 
Hi, in my experience with high end gaming PC's undervolting has reduced GPU temps without crashing or stuttering or drops in FPS in game performance. Underclocking has worked in some situations again without crashing or massive drops in FPS with reduced GPU temps. Repasting your GPU is definitely an option for you ONLY if you are comfortable with doing it. If not contact someone with experience with this procedure. Your GPU is a significant investment. Please kindly post your results. Just a suggestion from an old school PC builder and Gamer.
 
wow, this is a really toxic section.

Those are not normal temps, your thoughts are valid

I would suggest replacing the thermal paste
given that you have torn it down, I'm gonna gas you up and say you can do the paste for the gpu, take your time. More than likely gamers nexus has a tear down video.

I want to add, I have been using ptm and sheets on gpu's.
I had a kryosheet on my 4070 oc tuf, and it didn't go above 50c gaming and streaming.
I recently put ptm on my 5070, and oc +140mhz it is in the low 50sc gaming and streaming.

But thermal paste is still good.
I would say try the thermal paste change.

Since your hotspot temps aren't abnormal I would say the pads should be fine on the vrms, but that is something you could also check, but would not account for high gpu temp
